A condescending older person who lectures younger people.
Originally school slang for a strict teacher, now aimed at any senior — a boss, a relative — who demands deference and dispenses unwanted life advice. A sharp, modern, very online word.
Genuinely insulting. Never say it to the person you mean it about.
